Oma7144, why RKandroid tools do not see my tablet? I installed drivers, my PC see my tablet only in the APLLY UPDATE FROM ADB, I have Windows XP X32
[Miscellaneous Android Development] Oma7144:
Here is a Driver Assistant: http://crewrktablets.arctablet.com/?wpfb_dl=1187. Unistall driver first, then install.

- Oma -
[Miscellaneous Android Development] Oma7144:
Is this is pure V88 build, or did you change anything? What kernel do you use? Is the screen not rotating or just wrong orientation?

- Oma -
[Miscellaneous Android Development] St4mi:
Yes, just the Rom 2692. No it does not rotate at all.

The Study Tab Kernel.

Stami
[Miscellaneous Android Development] Oma7144:
I guess your tab comes with a genuine 3.0.8+ kernel and you use the 3.0.36+ study tab kernel now?

For rotation pls install this via CWM: http://crewrktablets.arctablet.com/?wpfb_dl=2712

- Oma -
[Miscellaneous Android Development] St4mi:
Exactly! It works now thanks. A bit laggy but works. ☺

Only thing that annoys me is that it sometimes softreboots when playing final fantasy record keeper and the Problem with kodi.

(Aber alles weitaus schneller und besser als das 4.2.2 Rom. Vielen dank. Auch der Akku hält viel länger und lädt schneller!)

Stami
[Miscellaneous Android Development] Oma7144:
Fine. Kodi is broken for LP on RK architecture.

To improve UI feeling disable all animation scales in developer options and use Nova launcher and set animation/scroll to "faster than light".

- Oma -
[Miscellaneous Android Development] St4mi:
Rotation seems to be "broken" it barely works.

Is there anything I can try except editing the build.prop? 0° 90° and 180° instead of 270°?

Stami
[Miscellaneous Android Development] Oma7144:
Do you mean rotation or orientation?

- Oma -
[Miscellaneous Android Development] St4mi:
Haha. I think rotation. Although sometimes it rotates to the other side when it works.

Btw, can the wifi problem be connected to the missing MAC adress?!

Stami

(Dein Postfach ist leider voll dewegen hier mal meine Nachricht.

Hi Oma,

kannst du mir wenigestens irgend einen Tip geben wie ich Final Fantasy Recod Keeper ( https://play.google.com/store/apps/details?id=com.dena.west.FFRK ) "fixe"?

Es ist die einzige App die immer crashed und das Tablet zum neustarten "zwingt" und so Grafikintensiv ist sie nicht.

Andere Apps wie Antutu oder beliebige 3D Games laufen einwandfrei. Bin halt etwas süchtig danach und würds gerne auch wieder aufm Tab zocken und nicht immer das Handy leer saugen. :)

Danke & VG

I have never seen this. I just got my stereo today. It is one of those Android Double Din stereos from China.

I already see a MAJOR issue that I cannot figure out. There are NO developer options.

In ABOUT device I select the build number many many times and it still does not unlock the developer options.

Hello guys,

recently my tablet powered off because battery 0%. But since then I cant boot it again. It stuck on booting logo of current ROM. I attached the log, maybe you can find out how to fix it. I haven't done a backup and don't want to loose actual installed apps, so reflashing as last resort... thanks for any suggestions... :)
[Miscellaneous Android Development] ildar_prophet:
Useless. You'd better get the adb log for the bootloop-ed system. If ADB is off on the system, then there are ways to turn it on from recovery. (with sqlite or alike).

If you boot the RIGHT recovery, you can make backup from it.

As the last resort you can backup data partition with rkflashtool.

Heads up!

Hello,

is there any possibility to download and install any rom for Odys Genio aka Xelios 7 Pro?

My tablet seems to be broken, it just constantly restarts without any reason....sometimes before the lockscreen appears, sometimes after. I would like to try to just install a new Rom and see if this might solve the problem. Can anybody help?
[Miscellaneous Android Development] ildar_prophet:
checking android-panic might help to see what happens.

Before installing some ROMs, it helps to make the factory reset first. 2nd, try with the latest official stock ROM for the device. 3rd, go on with other options, incl. other/custom ROMs etc.

[Miscellaneous Android Development] cannabis4711:
Hi,

thanks a lot for your reply. I tried to do a factory reset already (or I even managed to do it once when I was so lucky to open the settings in order to press the factory reset button....there somehow I was lucky enough and the tablet didn't directly restart, but I couldn't find out why this was the case....seems to be a random and very rare event), the above described problem appeared on the next day again and the tablet constantly restarts (again) since that.

I also tried to get into the recovery mode for wiping the tablet and resetting it there, somehow my tablet doesn't want to let me in into the recovery mode oO...i tried different combinations which I found on the internet, none of them worked (like pressing vol + button and power button for some time, same with vol - or bot together...with vol + and pwr button the tablet starts, if I stop pressing the buttons it just goes into the restart-bootloop again, if i continue pressing them, the tablet just switchs itself off).

Then I tried to download the stock ROM, which I couldn't find at the manufacturors homepage nor in any forum but I would be pleased if you would provide me one, but I would take a custom ROM aswell :D...any ROM that I could try to install. But this leads at the moment to the second problem that I have, when I connect the tablet to the computer, it is not recognised. I gues because it always restarts before being able to get recognised.

Thats why I don't know what to do and why I hope, that one of the clever experts might help me hopefully :D.

Edit:

My tablet just let me opening the settings for a few seconds. So I managed again to reset the tab. Now it "seems to work" again, like the last time. But I am a bit scared, that somehow this error appears again. I hope it will be only a software issue, so is there any possibility to download any ROM to install it over my actual version?

And how can I enter to the Recovery mode, as described above somehow it doesn't want to work for me.

[Miscellaneous Android Development] yurais:
Trying luck...

I have had a bootloop PORTO D110SJ (EM3066_816A)

RK3066 tablet for a year now without fix :(

there is no firmware for it that I can find, I have searched with board number and everything.

it is a 10 inches white tablet.

I would like to try a custom ROM, lile the latest lollipop posted here in OP, but since it is an unknown tablet, there is no kernel for it in the list and I dont have idea regarding which kernel I could use.

Can someone help me to fix this?

I have read a backup of the tablet firmware, I have access to stock param, stock kkernel image, stock recovery, etc.

I am not a newbie, so giving to me basic directions I can continue myself.

help if youi can

Hi Oma,

I made a small donation and just wanted to leave a message to say thanks on the ARK SITE but could not register. I entered a user name and e-mail but got no e-mail to complete the registration. I am 100% sure e-mail address is correct and even tried a different one. Anyway, just wanted to say thanks again for your hard work.

have a great 2017

[Miscellaneous Android Development] Oma7144:
Thank you!

I guess we are talking about this rom: http://crewrktablets.arctablet.com/?p=1913

And this kernel: http://crewrktablets.arctablet.com/?wpfb_dl=1173

Here is a parameter file for bigger kernel: http://crewrktablets.arctablet.com/?wpfb_dl=2499

- Oma -
[Miscellaneous Android Development] misterxp:
Bigger Kernel

Hi Oma! thanks!

I was getting worried...perhaps you had retired :)

Yes that Rom is the one I installed. To be honest, I managed to flash the bigger ROM but in a second stage (I flashed the small one and then flashed the bigger one). I did try to change some setting s but still was not able. Now I can see what I should have done! But to my surprise there was no difference (perhaps because it does not work if I install in a second stage) so I re-flashed everything again with original Kernel.. I will certainly try with the parameters you very kindly sent me but would like to use the ROM as it is for now. I have not had the chance to use it yet because I keep messing around with it ;) !. A part from the battery and brightness (no real problem because I never adjust the brightness and the battery I get a warning when it is running low) it works perfectly. I did once try the battery fix but it did not work because, as I saw later, I installed wrongly so will try again another time with the brightness fix. At the same time, I will also try to install the bigger Kernel too. I also can't make a back up. Not even with ADB (not even with various work a rounds and fixes I found) and not with CWM (get errors and then I have to flash everything again because) so, if I want to experiment, I have to re-install everything. I tried the various backup apps but I saw it is quicker to re-install everything. (not asking for any help just for information. It is not a problem for me really!)

For now I want to enjoy it! thanks again. I started to learn a bit about Android thanks to you and your team :D (till now I only knew Windows phone)

Bye and warm regards

Martin

p.s. I could not resist the temptation! re-flashed with the kernel you sent me and did the brightness fix. All is almost perfect....works better with 8mb Kernel

You know, your ROMs are still ones I remember with warm feelings. My old PIPO S3 still has CM10.1.

I recently unconserved it for HDMI and some experimenting.

Got an idea to replace GAPPS with MicroG. But to remove all of GApps I sill need CM/AOSP parts that were replaced by GApps files in lib and framework.

What do you think? will it still be possible to recover them?

Convenient file sharing. Think of it as Pastebin for files. Registration is not required. Large files are supported.

sorry it's a bit late.

[Miscellaneous Android Development] Oma7144:
1. for a successful flash it is necessary to secure that partition-layout fits for the new images

2. unfortunately we have a 3.0.8+ kernel running in a 3.0.36+ environment; if you like to use CWM you need to flash back the 3.0.36+ kernel; no other idea for the moment ...

3. can you please provide a logcat of Pipo S3 stock kernel and also a logcat while loading 8192cu.ko manually?

Edit: Run this fix directly after format_NAND fix. After first full boot flash the Pipo S3 kernel.

- Oma -
[Miscellaneous Android Development] ildar_prophet:
Then I suggest to change the line to this:

Like it?

Yeah. I know that.

Nothing very interesting.

I hoped that would work, but...

BTW, when insmod-ing the 8192cu.ko.3.0.8+, logcat shows nothing, but dmesg:

That all was on 20130501 version. Will try the last one (Update3).

oops, you're right. The last module you gave me produces different error message.

The "good-old"

you can see it on your tablet using:

# insmod wlan.ko ifname=wlan0 if2name=p2p0

dmesg say:

Oma7144, why there isn't a module for your custom kernel, but only for the stock kernel?

Anyway, thanks a lot for your efforts. I appreciate that.

Though with the updated libhardware_legacy.so Wifi raised up. *HAPPY* Yeah!

---------- Post added at 09:31 AM ---------- Previous post was at 09:20 AM ----------

As soon as Wifi is ready for PIPO S3, I promise you more testers from 4pda. :)))
[Miscellaneous Android Development] Oma7144:
So with stock kernel #234,

the 8192cu.ko.3.0.8+ from Pipo S3 stock image and the new libhardware_legacy.so in the v3.2 build

you will have wifi?

If so I will do a CWM fix.

- Oma -
[Miscellaneous Android Development] ildar_prophet:
Well, yes!

My current setup:

cRom v3.2 (4.2.2_20130518)

updated libhardware_legacy.so from this post

updated wlan.ko and the PIPO kernel from this post

+ Ad-hoc is back with Oma Wpa Supplicant Adhoc JB fix.

Wifi works.

(I assume some other kernel/wlan.ko combinations should work, didn't test it yet.)

Regarding cRom v3.2: I've found one little glitch: vold.fstab is changed to /sdcard -> mmc. I had to copy vold.fstab_old back to vold.fstab. 10 minutes of testing, something more can show up later.

Oma7144, again, great respect for your work!:good:
[Miscellaneous Android Development] ildar_prophet:
Oma7144,

by this:

do you mean that HW decoder doesn't work?

If so,

1. it means that a user has to use Software decoding, right?

2. then what's the big reason to do recoding == decoding + encoding (+ player side decoding) with uPNP? Is it easier to use just MX player's soft-decoding?

---------- Post added at 05:46 PM ---------- Previous post was at 05:03 PM ----------

One more thing I see on this cROM: can't install Android Battery Dog. It is very old app, maybe that's the reason.

As usually we have problems with HW decoding:

- Youtube working

- flash in browser working

- HW decoding of video codecs not working

If anyone has an idea, rockchip (!) code is here.

For the moment you can use SW decoding in MX-Player. This will give you full performance, yes.

If, for any reason (e.g. using window function of video.apk), you like to use HW decoding it is given via using BubbleUPNP.

Alright, I took the plunge... latest 4.2.2 beta with 6.0.3.1 cwm and the U30GT-H kernel kind of works. Data isn't persistent, so it forgets everything after a reboot.

Also, there seems to be no HW acceleration of the UI, everything seems pretty choppy :)
